Month: October 2014

On Oct. 23rd, 2014, just as the New Moon was about to pass in front of the sun, the students of Earth to Sky Calculus launched a helium balloon carrying a Nikon D7000 camera. Their goal: to set the record for high-altitude photography of an eclipse. During a two-hour flight to the edge of space, the camera captured 11 images of the crescent sun. The final picture, taken just a split second before the balloon exploded, was GPS-tagged with an altitude of 108,900 feet:

To put this achievement into context, consider the following: Most people who photographed the eclipse carefully mounted their cameras on a rock-solid tripod, or used the precision clock-drive of a telescope to track the sun. The students, however, managed the same trick from an un-stabilized platform, spinning, buffeted by wind, and racing upward to the heavens at 15 mph. Their photos show that DLSR astrophotography from an suborbital helium balloon is possible, and they will surely refine their techniques for even better photos in the future.

Hey thanks! The students wish to thank AutomationDirect.com for sponsoring this flight. Their $500 contribution paid for the helium and other supplies necessary to get the balloon off the ground. Note the Automation Direct logo in this picture of the payload ascending over the Sierra Nevada mountains of central California:

Another notable picture shows the payload ascending over clouds, which blocked the eclipse at ground level but did not prevent photography from the balloon.

Readers, would you like to sponsor a student research flight and have your logo photographed at the edge of space? Contact Dr. Tony Phillips to get involved.
